For ease of description, a packaging box 2 and a cushioning pad 1 and a sheet 4 that are disposed in the packaging box 2 are together referred to as a packaging assembly 3.

Referring to FIG. 1 to FIG. 5 together, the cushioning pad 1 provided in an embodiment of this application is described. The cushioning pad 1 includes a body 11 and a protrusion 12. The body 11 is disposed between two adjacent sheets 4 and is used to isolate the two adjacent sheets 4, to avoid friction between the two adjacent sheets 4 to cause damage to the sheets 4. The protrusion 12 is disposed on the body 11 and extends from an end of the body 11, and the extended part extends beyond a corresponding end of each sheet 4. Therefore, a number of sheets 4 can be learned rapidly only by examining the protrusion 12, thereby improving the efficiency of counting the number of the sheets 4. It may be understood that the packaging box 2 is used to carry the sheets 4, and the sheet 4 is not a part of the packaging box 2.

A plurality of protrusions 12 may be disposed around the sheets 4, to facilitate counting of the sheets 4 from a plurality of directions, so as to improve the efficiency of counting the sheets 4. The protrusions 12 are disposed in a corresponding groove 23 of the packaging box 2, so that it is convenient to count the protrusions 12, thereby improving the efficiency of counting the sheets 4. In addition, the groove 23 can further fit corresponding protrusions 12, thereby improving the safety of packaging the sheets 4, and the sheets 4 can alternatively be placed in a misaligned manner, thereby improving the efficiency of packaging the sheet 4. In another embodiment, the number and the positions of the protrusions 12 may also be adjusted according to an actual requirement, and are not uniquely limited herein.

The cushioning pad 1 may be made of an organic material, for example, an expandable polyethylene (EPE) material. Therefore, the cushioning pad 1 has relatively high elasticity and a desirable cushioning protection effect. In addition, the operation of counting the number of the protrusions 12 is facilitated. The cushioning pad 1 is formed by die cutting and stamping, so that processing and production are facilitated. In another embodiment, the cushioning pad 1 may be made of another material by using another processing process, and the material and processing process are not uniquely limited herein.
